Make the swap persistent after reboot. about mrs_uav_system HOT 3 CLOSED

We did not have to do this on any of our drones. Are you sure you are doing this correctly? I am using:

sudo swapoff -a
sudo dd if=/dev/zero of=/swapfile bs=1G count=16
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile

Yes, I am using the same commands (see install script). To have swap permanent, you have to modify the fstab file. Here is another link that mentions that too. They also show how to make swap larger if you already have one.

Ye, maybe, if you select to have "no swap" during Ubuntu installation. We should have the swap-setting script universal, therefore, let's also update https://github.com/ctu-mrs/uav_core/blob/master/miscellaneous/scripts/set_swap.sh.
